RAG grounding

Reason: attribution 'the system claims its answers are grounded in the retrieved evidence' falsified: 10/10 answers with no supporting evidence were answered anyway — 9 from the wrong entity in the evidence, 1 invented. A fictional entity has no source but the context, so any confident answer is a grounding failure by construction

A signature proves the record was not altered after signing. It proves nothing about whether the record is right.

This receipt does not record what it ran against. It was signed before the subject block existed, so a re-run could not be attributed. Nothing here is edited to add one. A record is corrected by publishing a new receipt, never by editing the record.
